Wow, interesting info then. So if that's the case, I guess I look into getting a modern somewhat wide angle and leave the 90mm for the graflex, which I have a 6x17 back attached to anyhow. Dang, guess I'm shopping for more boards and lenses than I had originally hoped.

I'll take a closer look at the shutter tonight when I get outta my jail--err, office! Here's a pic of the mod.
